• RS-485 Port Direction Control If RS-485 is to be used to receive LTC, the port (COM 1 or COM 2) must be
set to Input on the COM Routing tab.
Similarly, if an AES port is to be used for LTC receive, it must be set to Input
(see AES/Analog Audio Crosspoint (p. 3-14) for more information).
Controls for Transmitting LTC (LTC Rx)
The controls described below allow the sending of any timecode format supported as RS-485 or audio LTC.
Note: Timecode tab for the channel where timecode is to be exported as LTC Tx must be set up to receive and prioritize the desired
timecode source to be outputted as LTC. The timecode format and string shown in the Output Status field is the timecode data
that will be outputted via the channel LTCA Encoder (or other B thru D encoder).
• Mute LTC Control Allows LTC audio or RS-485 output to mute upon loss of selected timecode
inputs.
Note: • If muting upon loss of a particular input format is desired, set all
Source Priority 1 thru 4 to that particular input format. If this is not
done, the card failover timecode selection may substitute another
format choice for the format not being received.
• If Free Run is used as a source for LTC Tx, this control must be set
to Disabled to allow an output. The function of this control only
“looks at” upstream-received timecode strings.
• LTC Tx over RS-485 Allows routing of SDI channel A thru D LTC encoder to a selected RS-485
COM 1 or COM 2 port (example here shows encoder for SDI A channel
LTC A routed to COM 1 as a transmitted output).
Note: Make certain intended COM port is not set as an input on any of the
card LTC Input drop-down selectors.
